You can have the image script as part of the same PHP file, by checking
to see if it is being called for an image rather than a normal page, but
it just makes things more convoluted. Also, the base64 method will not
work in IE. I had a similar problem at work that could only be solved by
using a separate script to output the image. It can't be streamed inline
in a consistent manner.

I too prefer to have the image called from a separate page.
img src='getimage.php?id=12345'/
That way if the images are of differeing types (tiff/png/jpg/etc) I can
locate all the handling code in the getimage.php file and its becomes the
one place to handle this kind of stuff

Perhaps if you had been more specific about images in variables (it looks like you're using BLOBs, I had guessed you were using filenames and storing the images on disk... which is another argument altogether), my answer (or sarcasm, in your eyes) would have been more direct to your question. As for my solution not working--for BLOBs, no. Of course not. My analogy of your question, however, is a bit like this: Q: How do I turn on this light switch? A: You flip it to the 'on' position. ... Q: No, I mean how do I route power from the solar panels on my roof to produce a current that will be affected by this lightswitch? I don't see the reason for Base64 encoding anything, but I'm glad (also not sarcastic) that you got the answer to your question that you were looking for. I also hope that you learned to be more specific when you're requesting assistance, and not throwing someone's suggestions back in their face when they were just trying to lend you a hand with what they understood your question to be.

Header(Content-type: image/jpeg); REAL browsers like Mozilla and Firefox etc trust this. Microsoft, however, in its infinite wisdom, ignores standards-compliant Content-type: headers and guesses at the content type from the URL. Thus, odds are really good that some versions of IE on some versions of MS will decide that your image must be a JPEG. The only generalized solution I know of is to make sure you IMG tag *ends* with .jpg imt src=confirm_image.php/ie_sucks.jpg / IE (some versions) will see the .jpg and know it's a JPEG, and ignore the Content-type: ImageString ($image, 5, 12, 2, $code, $text_color); ImageJPEG($image, '', 75); ImageDestroy($image); Most people get a nice image but some people get only, what appears to be, garbage: ÿØÿàJFIFÿþ;CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), XXX The stuff above XXX... That doesn't look like valid JPEG starting characters in my experience... PERHAPS they're fine, or part of some new standard, but every JPEG I ever saw started with the stuff above It's possible that your code_bg.jpg has EXIF data and/or is a progressive JPEG, and that GD preserves that info, and that some browsers are incapable of displaying such a JPEG. For the complete output have a look here: http://www.samuel-area.de/phpbook/confirm_image.php The crucial thing here is that SOMETHING is forcing some kind of output and the Content-type: is being set to text/html on that server for that URL: -bash-2.05b$ telnet www.samuel-area.de 80 Trying 82.149.248.196...

So, most definitely, in this case, something is configured incorrectly on that server to over-ride your header() call and it's spewing out the JPEG as if it were HTML. My first guess would be some kind of security setting/module which is trying to be smart about .php which is forcing the final output Content-type: to be text/html, even though PHP is perfectly capable of generating ANY kind of content. Since it's an Apache server, if the trick above (end URL in .jpg) does not work, you could try this: #1 mv confirm_image.php confirm_image.jpg Now the URL will look JUST like a .jpg to everybody. #2 Edit a file .htaccess in that same directory as confirm_image.php and add this to it: Files confirm_image.jpg ForceType application/x-httpd-php /Files Now Apache knows that this particular .jpg file should be passed through PHP to generate output. #3 Change your IMG tag to point to: confirm_image.jpg If that STILL doesn't fix it, you're going to have to get the administrator of that server to figure out why their server insists on spewing out Content-type: text/html for a dynamic JPEG. -- Like Music? http://l-i-e.com/artists.htm -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
